During F1 weekends when I used to live in Montreal I just roamed around and sucked up and enjoy the festivities and the atmosphere. Wouldn't even think of hobbying. It is a mess all around from logistics, traffic and service/personality wise. Plus all the hotel rooms are jacked up in price or booked solid. Absolute mess. During this time every girl is an SP. Better to let all these naive tourists have their fun and take since many wouldn't know what quality service is.
